system broken

Thu Oct 22 04:36:51 EDT 2020

yeah, i found that it is broken too.
i tested on few octeon boards and all of them fall in ‘high memory device’ category.

reverting commit brings back the working tree back.

i would suggest to revert for now and do better testing next time.

also when you start a fresh built from initramfs - it boots bot gives lots of segfaults:

> system doesn't work properly. After sysupgrade, system does not restart completely and hangs somewhere in the boot process. I've to do a hard reset. After this, system does boot, but password is reset to no password. I don't know if other settings are reset too. ubusd is not started. uhttpd fails to start, because ubus socket isn't available. If I apply a previously saved backup with 'sysupgrade -r ...' and force a reboot, system starts, but tries to initialize a ext rootfs, which doesn't exist, and hangs in the boot process. At this point, I've to do a recovery via uboot. My router is a tp-link Archer C7.
